2.2.1 Detaching the Sensor

The ISOTMP35BEVM functions with or without the sensor breakout board. However, to evaluate the ISOTMP35 in high voltage high temperature applications, the sensor breakout board must be detached to disconnect the breakout sensor board. To detach the sensor board and reconnect correctly, follow these recommendations:

  • De-solder bridge connectors from pads on both side.
  • Break off the sensor board from the controller board along the perforations.
  • Reconnect sensor board and controller board with wires soldered to labeled pads. The signals traveling across these wires are low voltage, however the wires themselves must be rated to handle high-voltage levels.
Important: Depending on the application, the sensor board can be connected in such a way that the wires connecting the EVM cross over other high voltage signals or components. If low voltage rated wires are used in that case, then the wires and EVM can be damaged if the wires and EVM come into physical contact with a high voltage signal.

The user can also choose the voltage on the sensor breakout board 3.3 V & GND pads. The ISOTMP35 can accept any supply voltage from 2.3 V to 5.5 V.
